SPRING BED AND SEAT BOTTOM.

SPECIFICATION forming part of Letters Patent No. 639,224, dated December `19, 1899. Application tiled January 16, 1899. Serial No. 702,350. (No model.)

To all whom t may concern:

Be it known that I, JOHN F. GAIL, a citizen of the United States, residing at Kenosha, in the county of Kenosha and State of W'isconsin, have invented a new and useful Spring Bed and Seat Bottom, (Case 0,) of which the following is a specification.

For convenience in making cross-reference this application is designated Case C, and four other applications forLetters Patent for bed-bottoms executed by me of even date herewith are designated, respectively, Case A, Case B, Oase D, and Oase E.

This invention relates particularly to spring bed-bottoms formed of vertical spiral springs united horizontally by tie-rods.

The improvement involvesthc use of a new form of tie-rod which permits the use of the simplest form of vertical spiral springs and which allows the ready assembling of the parts of the bed-bottom to constitute the iinished structure. There is economy in the ready assembling of these parts, and there is also economy in the use of a simple form of the spiral spring.

My improvement results in a structure which hasa high degree of strength, a distribution of strain applied at any particular point, and an even surface.

In the accompanying drawings, Figure lis a plan of a portion of a bed-bottom embodying my improvement. Figs. 2 and 3 are detail views of the construction shown in Fig. l. Figs. 4, 5, 6, and 7 illustrate modilications. A

Inasmuch as the general construction of bed-bottoms of this class is well known, I deem it sufficient to illustrate only portions of bedbottoms showing the application of my irnprovement.

Referring first to Figs. l and 2, A is a rectangular frame forming the margins of the bed-bottom. This frame may be of wood or metal; but it is preferably made of metal rods or bars somewhat heavier than the metal of the springs and tie-rods.

B B are the springs. These are arranged in rows parallel to the sides of the frame A and are in vertical position and of spiral form, the upper end of each being formed into a cornplete ring B' by knotting or in any other suit-4 able manner. The springs maybe cylindric in outline or they may be conical or double conical. As already stated, it is the object of the invention to embody the Well-known forms of vertical springs into a bed-bottom of superior quality and the parts of which may be readily made and readily assembled.

O is a tie-rod extending transversely across the bed-bottom and over one row of springs, near the edges of the latter, and having its ends suitably attached to the frame A. At each spring said tie-rod has three upward bends Ol, two over the ring B and one midway between said two. Said two upward bends may be so great as to allow the main portion of the tie-rod to rest below the level of the ring B. j

C2 are loops extending laterally from the tie-rod C at each spring B to the adjacent spring of the next row or to the side of the frame. Each loop is formed by folding wire into substantially a V shape, the two ends of the wire extending beneath the ring B and thence over and around the tie-rod C, preferably at one of the bends O. The portion of the loop the farther from the tie-rod O is bent into vertical form (marked C3) and passes beneath and then upward through the ring B of the adjacent spring of the next row of springs.

The transverse row of springsv B adjoining the frame A are united to said frame by one of the tie-rods C, the loops C2 extending partially around the said frame.

Another set of tie-rods D D, for convenience designated as key-rods, are arranged at right angles to the tie-rods C. These are straight (though they may be crimped at points where they bear on other parts, as

Ashown in Fig. 7) and extend centrally over the longitudinal rows of springs B and beneath the vertical part O3 of each loop C2 in the row of springs traversed by said key-rod. The ends of the key-rod D may be suitably secured to the frame A, preferably in engagement with a loop C2, engaging the frame at that point, the rod reaching through the loop. A

It will now be seen that the bed-bottom herein described consists of only live kinds of parts-namely, the frame A, the springs B, the tie-rods C, the loops C2, and the keyrods D; and it will now be understood that the assembling of these parts to form a complete bed-bottom is a simple process involving only the use ot' the hands and a simple bending-tool for securing the ends of the tierods and key-rods. The frame may be iirst put into position and the springs then placed in rows within the frame and the tie-rods C then put into position with reference to the springs and the frame and the ends of said tie-rods bent around the frame or secured in any suitable manner. The loop C2 may be applied to the tie-rod C before the latter is applied to the frame and springs or after the tie-rod is in position.

In Fig. 5 the loop C2 after passing beneath the ring and over the tie-rod passes onward and again beneath the ring and then around the tie-rod.

In Figs. 4, 6, and 7 the vertical part C3 of the loop is turned downward instead of upward. This requires the key-rod to pass beneath the adjacent spring-ring and through said part of the loop.

In Fig. 6 the tie-rod C passes beneath the spring-ring, and the loop C2 extends over or upward through said spring-ring.

The key-rods D D may have their ends secured to the frame, as shown in Fig. l. This results in a very positive interconnection of the springs and the forming of such a surface as will not yield unduly7 at any one point, pressure at any point involving the depression of a considerable area of the bed-bottom surface. The factis also to be noted that the key-rods D, extending midway over the rings B, prevent the central portion of the spring from pushing upward through the ring B, as is sometimes the case when the upper portion of the spring is left unprotected.

It should be noted that the loops pass or enter the plane of the spring-ring only far enough to let the key-rods pass under strain.

It will be understood that the number of tie-rods C Will depend upon the number of rows of springs extending in the direction of said tie-rods.

It will also be understood that my invention may be applied to spring-seats and that the foregoing description is applicable to spring-seats as well as to spring bed-bottoms.

The constructions shown herein in Figs. 2, 3, and are also described, but not separately claimed, in the application designated as Case A, to which reference has been made. The form illustrated herein by Fig. 5 is specifically claimed (in comparison with the claims herein made) in Case D,77 and in Case E there is illustrated, but not separately claimed, a construction embodying the features (as to the loop) illustrated by Figs. 2 and 5 of this application.

No specific claim is herein made for a keyrod having a bend where it crosses the ring of the spring, as illustrated in Fig. 7 of this application This feature is claimed in Case E, filed simultaneously with this application.
